Checkout Procedure
!
WARNING: Risk of Explosion or Fire.
Follow this or an equivalent checkout procedure
after installation. Before leaving the installation,
verify that the gas valve functions properly and that
the system has no gas leaks. Gas leaks can lead to
an explosion or fire, and may result in severe
personal injury or death.
Make sure all components are functioning properly by
performing the following test:
1. Test all joints and connections for leaks with a
soap solution.
2. Close the main upstream shutoff valve and wait at
least 5 minutes for unburned gas to escape from
the appliance, and then reopen the shutoff valve.
3. Turn on the main electrical power switch and close
the thermostat contacts. The appliance should
operate in accordance with the manufacturer’s
specified sequence of operation.
4. Turn the thermostat to a low dial setting to open
the contacts. All burner flames should be
extinguished. Repeat Steps 3 and 4 at least three
times.
5. Return the thermostat to a normal setting before
leaving the installation.
Regulator Adjustment
!
WARNING: Risk of Explosion or Fire.
Do not adjust the minimum flow rate of the valve
below the minimum safe working rate of the
appliance. This may cause gas leaks, which can
lead to an explosion or fire, and may result in severe
personal injury or death.
IMPORTANT: Refer to and follow any specific
instructions issued by the appliance manufacturer
with regards to servicing their equipment.
The pressure regulator is adjustable and has been set
to a specific customer requirement. If a different
setting is desired, follow these instructions.
1. Shut off all gas to the appliance.
2. Turn the thermostat to the lowest setting or Off
position.
3. Remove the pressure tap plug at the valve outlet
or in the manifold pipe downstream of the valve.
4. Install a manometer or pressure gauge suitable for
measuring the desired orifice pressure.
5. Remove the seal screw at the end of the regulator
stack.
6. Turn the gas on and place the thermostat at the
highest setting to cycle the system.
7. Allow the system to stabilize. Adjust the screw in
the regulator stack to the desired reading on the
manometer. (Turn clockwise to increase the outlet
pressure and counterclockwise to reduce the
outlet pressure.)
8. Reinstall the seal screw, which incorporates the
proper size hole for venting to the atmosphere. (It
may be necessary to cycle the valve several times
to verify the desired outlet pressure.)
9. Turn off the gas supply and place the thermostat
at the lowest setting.
10. Remove the pressure manometer and reinstall the
pressure tap plug.
11. Turn the gas on and set the thermostat to the
desired setting.
12. Check for leaks at the pressure tap plug with a
soap solution before leaving the site.
